STREET-CLOCK.

SPECIFICATION forming part of Letters Patent'No. 364,971, dated June14-, 1887.

' Application filed March 1, 1857. Serial No. $19,278. (No model.)

Be it known that I, ADOLPH. STAIB, a citizen of the United States,residing at Baltimore, in the State of Marylaud, have invented certainnew and useful Improvements in Running Street-0locks, of which thefollowing is a specification.

My invention relates to improvements in street-clocks which aresuspendedfrom the front of buildings.

The invention has for its object to provide a simple and cheapconstruction whereby the hands of such clocks may be driven by themovement of an ordinary cheap clock located inside of the building. I

The invention will first be described, and then designated in theclaims.

Referring to the accompanying drawings, Figure 1 shows an inside view ofthe streetclock, being a vertical section on the line at z of Fig. 2,looking toward the right. Fig. 2.is a vertical diamctrical section of astreet-clock on the line y 3 of Fig. 1. Fig. 3 is a plan and partsectional view of certain parts of the mechanism, such as may be seenbelow the horizontal .line 2 .2. Figs. 4 and 5 are views of thecounterbalanced hand. Fig. 6 is a View representing the street-cloclqthebuilding-wall, inside clock, and the connection between the two. Fig. 7shows that the connecting-rod which drives the hands of the street clockis attached to the arbor of the minutehand of the inside clock.

The street-clock has two dials, a, one at each side. Each dial issupported on suitable boards, I) b, and between the boards all themechanism is placed. A vertical bar, 0, is attached by blocks d andscrews d to the dial-board b, and has position midway between the twoboards. All the mechanism is supported on this bar. There are duplicatesets of mechanism, a different set being at opposite sides of the bar 0.One set only will be described.

The minute-hand e is attached to a hollow arbor, e, which has abevel-wheel, g, a pinion, 7t, and an arm, 2', projecting in an oppositedirection from the minute-hand and carrying a weight, 1'. The gravity ofthe weight is adj usted to suit that of the minute-hand, to which itacts as a counterbalance. A horizontal pin, j, is fixed rigidly to thebar 0 and serves as a supporting-journal for the hollow arbor e.

A-hanger, F, has its upper end secured to the vertical bar (J,which hasa holeflc. A screw, It, through the end of the hanger and into said holesecures the hanger. The said hanger has a branch arm, I, which supportsa shaft, and a large pinion, m, and a small one, m, both mounted on thesaid shaft between the hanger and its branch arm. The large pinion an engages with the pinion it on the minute-hand arbor e.

The hour-hand a is attached to a hollow arbor, n,carryingalarge pinion,0,which engages with the said small pinion m. Thus a train of gearingconnects the two hollow arbors.

The driveshal'tpis supported by two brackets, q, attached to the barOone at each side. This shaft passes through the bar and turns freely ina hole, r, therein. The said driveshaft carries a bevel-wheel, p, whichgears with the two bevel-wheels g of the minutehand arbors of theduplicate sets of mechanism, as shown in Figs. 2 and 3.

The construction of the two dial clock, which embraces the bar 0,scoured only to one of the dial-boards I) and supporting the duplicatesets of mechanism wholly on said bar, is new and useful, as thereby allof the mechanism may be first fully adjusted and then the movabledial-board Z) placed in position.

The duplicate mechanisms are inclosed in a water-tight case, S, and thewhole is suspended on the outside of and beyond the wall T of a buildingby a suitable hanger,- U. An ordinary eight-day clock, V, has positionon the inside of the wall, and the arbor w of'its minute-hand w isconnected by a rod, I, with the drive-shaftp of the street-clock. A11important auxiliary in connecting the movement of the inside clock, V,with the street-clock S is the universal-jointed coupling L, of whichthree are employed. This coupling is plainly shown in Figs. 1 and 3,andwill be recognized as a well-known device. It compensates for any wantof trueness or precision of adjust ment of the street-clock with respectto the inside clock, and it obviates the ill effects that wouldotherwise result from any slight swaying or tremor of the street-clockoccasioned by the wind.

The finished clock represents an openface American stem-winding watch.

Having described myinv'ention, I claim and desire to secure by LettersPatent of the United States 1. In a street-clock, the combination, withthe boards having dials, of a bar interposed midway between andconnected to one of said boards and having secured on opposite sidesthereof a train of gearing, the journal-pins rigidly secured to the barand having loosely thereon inner and outer hollow arbors for the minuteand hour hands of said clock, and counterbalanceweights secured to theinner arbors, as shown and described.

2. In a street-clock, the combination, with the boards having dials, ofa bar interposed midway between and connected to one of said boards andprovided with a shaft having a bevel-wheehthe hangers on opposite sidesof shown and described, andfor the purpose set.

forth.

In testimony whereof I affix in y signature in the presence of twowitnesses.

ADOLPH STAIB.
